Abstract

The model FLUPOL describes urban pollution in times of rain linking up with the characteristics of rain, collecting basins and the collecting network. It enables simulation, upstream from an urban catchement area decontaminated by one or more networks, of the hydrograms and pollution flows engendered by any rain occurence and characterized by a certain number of variables and takes into account a succession of phenomena from accumulation of waste deposits on the ground to a possible suspension of sediments in the channels. After a short description of the model, its measurement and validation are carried out with the help of different measurements carried out in various French catchement areas.
